OK, this is difficult to explain but bear with me... Here's a simplified example [hrmsoftware.com]
We have a spreadsheet (table in green) inside another table (red) at width 100%. Because the sheet can get quite big we want to have the inner table scrolling (using a DIV; shown in blue) whilst the outer table at 100% stays at 100% screen width.
I just can't get it to work though... What I'm trying to achieve might be clearer if you look at the full prototype [hrmsoftware.com]*. Only need it work in IE5+
Taking on board tedsters comments I've managed to get it to [url=www.hrmsoftware.com/test/k011-scroll.htm]this...[/url] (click show market data to see more stuff for testing) nearly there except when your window is pretty small, the two tables size differently.
I imagine there probably isn't a way around this...
